CPunch 8cd0112c48 fixed __getter and __setter tables 2021-01-12 18:27:29 -06:00
CPunch 32162ce50c Updated examples and README to use proper syntax 2021-01-12 17:49:16 -06:00
CPunch ab86e19cfe Added ':' invoke operator 
You're now forced to use ':' when calling a method on an object. Some of Lua's ideas really are just better in practice /shrug

CPunch c510c9aebf Minor table refactor, added cosmoV_compileString and loadstring() to baselib 
cosmoV_compileString is recommended since it'll push the result (<error> or <closure>) onto the stack.

also, fixed some GC-related bugs, so yay!

CPunch 75b571c09a Added table support to the parser 
a new instruction, OP_NEWARRAY has been added. this instruction will create a table out of the uint16_t values on the stack, with incremental keys [0-(u16-1)]

CPunch 824c0e89b9 Dictionaries -> Tables 
Tables are going to become a more generic form of data storage. While objects will be "stateful", tables will remain static.

'{}' now refers to an object declaration, '[]' will be reserved for tables.

CPunch e57c194837 minor fix for OP_INVOKE 2021-01-07 20:04:42 -06:00

CPunch 860f30f201 removed printStack() from cosmoB_pcall() 2021-01-05 22:46:04 -06:00
CPunch eb2f50e456 Added CObjError, cosmoV_throw(), pcall(), and cosmoV_printError() 
Errors are now handled very differently, parser errors and VM errors are now treated the same.
When cosmoV_error is called, cosmoV_throw is also called, which formats the error object and sets the panic state.
state->error now points to the latest CObjError when state->panic is true. To get a nice formatted Objection message, use
cosmoV_printError() and pass the state->error. pcall() was added to the standard base library. When called, the first argument
passed is called with the subsequent arguments given. If the call completed successfully, `true`,`nil` is returned. However
when an error occurs during the call, `false`,`<error>` is returned. Simply print the `<error>` to retrieve the error string.

cosmoV_error now pushes the error string onto the stack, as well as uses cosmoO_VFString to format strings.
cosmoV_concat is now entirely self contained, and is now stack based. Push the CValues you want to concat into strings onto the stack and call cosmoV_concat with the # of values you pushed.
